These structures include logical-to-physical (L2P) mapping table portions that point to the respective physical blocks. When garbage collection is performed on a block, table region structures for that block, and another (e.g., the next block to be garbage collected) are read to avoid loading L2P table regions that do not point to the block. If any of the read portions of the L2P table region fail to point to either the block or the other block, these L2P table portions are removed from the loaded table region data structures.
